Description du projet
Pomper une chaleur efficace du point de vue énergétique dans les bâtiments
Dans la mesure où les progrès sont constants dans le domaine des bâtiments et constructions durables, les améliorations doivent tenir le rythme de la demande croissante de services énergétiques. Les bâtiments européens représentent actuellement 40 % de la demande énergétique et 36 % des émissions de CO2 liées à l’énergie. La décarbonation des bâtiments déjà existants en Europe est donc vitale pour que l’UE atteigne ses objectifs de protection du climat. Le projet HAPPENING, financé par l’UE, développe, dans cette perspective, une solution reposant sur des pompes à chaleur décentralisées faciles à installer, peu intrusives pour les occupants et facilement adaptables à un grand nombre de conditions différentes. Le projet déploiera également de nouveaux modèles financiers et commerciaux pour garantir la compétitivité des coûts.
Objectif
Currently, buildings are responsible for 40 % of the energy demand and 36% of the CO2 emissions in Europe. Decarbonisation of existing buildings plays a key role in order to reach the overall climate protection targets. However, current renovation rates lie in the order of 1%.
Heat pumps are a key technology in bringing renewable shares into heat supply of buildings; especially their combination with onsite renewable electricity production e.g. by PV allows to bring high renewable shares. Their current installation in existing multi-apartment buildings is however still marginal.
The proposed technological solution is based on decentralized heat pumps, in such a way that it results an easy-to-install solution for installers, low-intrusive for the occupants and easily adaptable to a large number of different building situations. This is flanked by developing near-zero planning, implementation and operation processes, in order to facilitate the work during the planning phase, ensure a high-quality installation and effective operation, and reduce the efforts and costs within the whole retrofitting project. The challenge of cost-competitiveness is addressed by developing new financial and business models. Bringing new players (such as financial experts) and financing models to the renovation market is expected to bring the needed paradigm change and boost investments in the residential retrofitting sector. Dissemination of measured performance and system characteristics from HAPPENING will be one of the key results of the project.
Through 3 demo sites (Spain, Italy and Austria), the project will demonstrate a highly versatile, scalable and replicable solution package for buildings energy system retrofitting allowing 70-75% of renewable energy fraction, 30-50% of PE and GHG savings, reduction of planning time by 50% and installation/operation time by 30% and payback time for ESCOs and investors of less than 8 years, compared to best available solution existing today.
